Book excerpt: Total knee arthroplasty (TKA) is the current standard of care for patients with severe osteoarthritis in their knee. In TKA, the damaged articular surfaces of the femur and tibia are replaced with orthopedic implants (i.e. the femoral and tibial components respectively). However, 20-25% of these patients report dissatisfaction after TKA using the traditional method of TKA, mechanically aligned TKA. By 2030, the prevalence of dissatisfaction could be 700,000 patients/year based on projected estimate of 3.5 million TKAs/year in the United States alone.The primary determinant of the clinical outcome of TKA is the alignment of the femoral and tibial components relative to their respective bones. The mechanically aligned TKA references anatomic landmarks that are unrelated to the function of the knee. A relatively new method for aligning the components, kinematically aligned TKA (KA TKA), references the articular surfaces with the goal of restoring the alignments of the limb, knee, and joint lines, and hence native knee function.Although patients report higher satisfaction and function at 6 months to 6 years after KA TKA, two unavoidable changes may prevent KA TKA from restoring passive knee function. The first is the replacement of the articular surfaces with implants of discrete sizes and average shapes. The second is resection of the anterior cruciate ligament (ACL). Accordingly, the overreaching aim of this research was to provide objective evidence using controlled in vitro experiments to evaluate passive joint function before and after KA TKA. Four metrics were determined to evaluate passive joint function: (1) the laxities (relative displacement of the tibia to the femur in a degree of freedom under an applied load), (2) the neutral positions (relative position/orientation of the tibia to the femur in a degree of freedom with no loads applied), (3) the contact force balance (difference between the contact forces in the medial and lateral compartments), and (4) contact kinematics (i.e. motion of the contact locations of the femoral component on the tibial component during flexion). Aim 1: Laxities and Neutral PositionsTo determine whether either or both of these unavoidable changes prevent KA TKA from restoring to native the laxities and neutral positions, the primary objectives were to determine how well KA TKA prevents clinically important (1) changes in the laxities and (2) shifts in the neutral positions in varus-valgus rotation, internal-external rotation, anterior-posterior translation, and compression-distraction relative to those of the native knee. The eight laxities and four neutral positions were measured from 0° to 120° of flexion in 30° increments in 13 native human cadaveric knees before and after KA TKA using a six degree-of-freedom load application system. The prevalence of clinically important changes in the 65 measured values (13 knees x 5 flexion angles) of each laxity after KA TKA was relatively low for all eight laxities. The highest prevalence occurred in external rotation laxity (21% exceeded 3.6°) and the lowest occurred in compression laxity (0% exceeded 1 mm). The prevalence of clinically important shifts in the 65 measured values of each neutral position after KA TKA was relatively low for internal-external rotation (20% exceeded 5°) and varus-valgus rotation (5% exceeded 1.5°), but was relatively high for the anterior-posterior (69% exceeded 1.1 mm) and compression-distraction (38% exceeded 1 mm). Aim 2: Laxities and Neutral Positions Imbalanced contact forces (> 67 N) and abnormal contact kinematics (i.e. anterior translation of the contact locations) of the femur on the tibia during passive flexion are associated with reduced satisfaction and limited flexion respectively after total knee arthroplasty (TKA). Although high satisfaction and function have been reported after kinematically aligned TKA (KA TKA) at 6 months to 6 years, no study has determined how well KA TKA prevents clinically important imbalances and abnormal contact kinematics during passive flexion. Accordingly, the objectives were to determine in vitro how well KA TKA prevents (1) imbalances between the contact forces in the medial and lateral compartments greater than 67 N, and (2) anterior translation of the contact locations in the medial and lateral compartments over an arc of flexion from 0° to 120°. The contact forces and contact locations were determined in both the medial and lateral compartments from 0° to 120° of flexion in 30°increments in six human cadaveric knees following KA TKA using a tibial contact force sensor implanted in place of the standard cruciate-retaining tibial component. The average contact forces remained balanced within 18 N, and the prevalence of clinically important imbalances in the 30 measured values (6 knees x 5 flexion angles) was 7%. The contact locations in both compartments translated posteriorly in all six KA TKA (i.e. prevalence of anterior translation = 0%) by an average of 16 mm and 18 mm in the medial and lateral compartments respectively from 0° to 120° of flexion. Conclusions KA TKA prevented clinically important changes/shifts in >̲ 79% of the measured values in ten of the twelve laxities/neutral positions, prevented clinically important contact force imbalances in 93% of the measured values, and prevented abnormal contact kinematics 100% of the knees despite the two unavoidable changes. These findings also help to explain the previously published clinical results that show KA TKA has a low risk of failure at 6 years and leads to high patient satisfaction and function at 6 months to 6 years which adds to the ever-growing compilation of evidence that justifies KA TKA as an acceptable alternative to the traditional alignment goals for TKA.

This book was released on 2021-06-29 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calipered kinematic alignment was proposed by Dr. Stephen M. Howell to enable the accurate and individualized placement of total knee components coincident within ± 0.5 mm of the patient’s pre-arthritic alignment. The aim was to restore the patient's native joint kinematics and thereby address the well documented 20% dissatisfaction when total knee replacement is performed using traditional, or mechanical alignment techniques. With Dr. Stefano A. Bini and Dr. G. Daxton Steele as co-editors, Dr. Howell has curated an international team of expert surgeons and engineers to discuss various aspects of the calipered knee alignment technique in short, concise, and well-illustrated chapters. Each author provides clear, practical guidance for adopting and implementing calipered kinematic alignment covering manual, patient-specific, navigated, and robotic techniques. Chapters on component design tailored explicitly for kinematic alignment and showing the close relationship between knee biomechanics and the kinematically aligned TKA help the surgeon manage complex challenges associated with deformity and post-operative complications. Following the introduction of the calipered kinematic alignment technique for total knee arthroplasty, many international studies have shown consistently better patient satisfaction than the traditional mechanical alignment technique. Better function and high long-term implant survival have catalyzed a paradigm shift in total knee replacement philosophy that is being embraced by orthopedic surgeons and innovative implant companies around the world with excellent results. Calipered Kinematically Aligned Knee Arthroplasty is the definitive textbook on the subject and features: Thorough explanations of how the calipered kinematic alignment technique for total knee arthroplasty accurately sets total knee components coincident with the patient’s pre-arthritic alignment and coaligned with the three rotational axes of the native knee. A personalized approach to total knee surgery designed to reconstitute the patient’s native biomechanics in contrast with mechanical alignment that place all patients in the same standard alignment regardless of their constitutional anatomy. Detailed and well-illustrated descriptions of manual, navigated, robotic and patient-specific guide techniques that confirm kinematic alignment with a caliper. Clinical photos, radiographs, and line art throughout the book as well as helpful online technique videos. Key focus topics such as managing complex deformities, the expected post-operative recovery, and future trends in kinematic alignment. The shared experience and knowledge of international pioneers in the field. An emphasis on a personalized surgical philosophy which enables same-day discharge, reduces pain and opioid use, and promotes quicker recovery, better function, and a more natural feeling knee.

This book was released on 2023-08-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern field of total knee arthroplasty began over 50 years ago in the 1970s when the FDA approved cement for implant fixation, and durable plastic that replaced the meniscus became available. Simultaneously, alignment evolved into two opposing and contentious philosophies, the anatomic approach (forefather of kinematic alignment, ) and the 'cookie-cutter' or mechanical alignment. In 2006, the concept of personalized surgery initiated a paradigm shift away from the philosophy of mechanical alignment to calipered kinematic alignment total knee replacement. Dr. Howell, a professor of biomedical engineering and a sports medicine surgeon, developed the kinematic alignment technique. To perform the surgery, he created the first commercially made patient-specific guides designed to assist the surgeon in setting the components coincident to the patient's pre-arthritic joint lines, which is the kinematic alignment target.In 2007, early adopters' clinical experience, particularly Dr. Meade, persuaded over 300 surgeons to perform more than 20,000 kinematically aligned total knee replacements by 2011. Between 2011 and 2020, many worldwide studies reported that kinematic alignment improves patient satisfaction, function, ease of recovery, soft tissue balance, flexion, and joint-line and limb alignment compared with mechanical alignment. It is a winning approach.This primer uses the familiar concept of the Ten Commandments and selects ten topics for the surgeon to follow. The success of kinematic alignment requires caliper measurements of bone resections and intraoperative recording of verification steps. These recommendations reduce the risk of complications, a topic of great interest to the patient! Patients that research options in total knee replacement surgery will come across the kinematic and mechanical alignment philosophies. The mechanical alignment technique is a 'cookie-cutter' approach that places the components the same way in everybody regardless of their legs' shape. Because the method changes the patient's joint lines, the healthy ligaments are released, making the replaced knee feel unnatural. Kinematic alignment restores the patient's knee alignment before arthritis developed and preserves healthy ligaments, promoting patient satisfaction and high function.We hope this primer is useful for those investigating knee replacement surgery. Those who chose kinematic alignment, ask your surgeon whether they use the caliper and intraoperative verifications to position your new knee optimally!

Download or read book Do Varus-valgus and Internal-external Malalignments of the Femoral Component in Kinematically Aligned Total Knee Arthroplasty Cause Clinically Important Changes in Contact Force Imbalance and Laxities of the Tibiofemoral Joint? written by Jeremy Alan Riley and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple metrics are used to evaluate knee function after total knee arthroplasty (TKA). One is the contact force imbalance between the medial and lateral compartments of the tibiofemoral joint. A second metric is the laxities of the tibiofemoral joint. Measuring contact forces in vitro is relatively fast, however measuring laxities in vitro is relatively slow. It is unknown how long the laxities in a human cadaveric knee can be measured before the soft tissues of the knee significantly degrade. Accordingly, the first aim of this research was to determine how many days laxities can be measured in a human cadaveric knee specimen with a TKA before clinically important changes occur. The goal of kinematically aligned total knee arthroplasty (KA TKA) is to restore native alignments of the limb, knee, and joint lines with the intent of restoring knee function to native without ligament release. During KA TKA there are two steps to set the alignment of the femoral component. First, the two distal condyles are resected, setting the varus-valgus (V-V), proximal-distal (P-D), and flexion-extension (F-E) degrees of freedom. Second, the two posterior condyles are resected, setting the internal-external (I-E) and anterior-posterior (A-P) degrees of freedom. The medial-lateral (M-L) position is set visually. The femoral component is kinematically aligned when the thicknesses of the distal and posterior resections of the femoral condyles are equal to the thicknesses of the corresponding portions of the femoral component after compensating for cartilage wear and kerf of the saw blade. However, the use of manual cutting guides and oscillating saws can lead to errors in making these resections. Errors in these resections can cause femoral component malalignment. Two important errors are V-V and I-E malalignment. These errors can lead to condylar lift-off, pain, tibial component loosening, early implant failure, and need for revision surgery. Additionally, it is also unknown whether changes in the laxities are correlated to changes in contact forces or contact force imbalance. This correlation is of interest to guide surgeons in assessing the alignment of the femoral component by checking laxities to determine whether tibial contact forces are balanced without direct measurement of these forces. Accordingly, the second aim of this research study was to determine: (1) whether 2° or 4° of V-V malalignment of the femoral component in KA TKA causes clinically important changes in contact force imbalance and laxities, (2) what degree of V-V malalignment causes a clinically important change in contact force imbalance of 67 N, and (3) whether each of eight changes in laxities was correlated to changes in medial contact force, lateral contact force, and contact force imbalance due to V-V malalignment. The third aim of this research study was to determine: (1) whether 2° or 4° of I-E malalignment of the femoral component in KA TKA causes clinically important changes in contact force imbalance and laxities, and (2) whether each of eight changes in laxities was correlated to changes in medial contact force, lateral contact force, and contact force imbalance due to I-E malalignment. Aim 1 KA TKA was performed on three human cadaveric knee specimens. The laxities and neutral positions in four degrees of freedom were measured for seven consecutive days using a six degree-of-freedom load application system. The earliest statistically significant and clinically important changes were found at the end of day 4, when the varus laxity (3.3° ± 1.3°) was significantly greater than the varus laxity at the beginning of day 1 (1.9° ± 0.5°, p 0.01). Aim 2 KA TKA was performed on ten human cadaveric knee specimens. V-V malalignment was introduced using 3D printed femoral components which simulated errors in the joint line of 2° varus rotation, 4° varus rotation, 2° valgus rotation, and 4° valgus rotation. Contact forces were measured using a custom tibial force sensor. Laxities were measured using a six degree-of-freedom load application system. A simple linear regression related the degree of V-V malalignment to the change in contact force imbalance. The correlation coefficient was computed for each combination of the eight changes in laxities and the changes in medial contact force, lateral contact force, and contact force imbalance. Statistically significant and clinically important changes in contact force imbalance occurred at 0° flexion with 2° varus (103 N), 4° varus (211 N), 2° valgus (89 N), and 4° valgus (178 N) malaligned femoral components (p 0.0010). A nearly perfect straight line (R2 0.99) relating the change in contact force imbalance at 0° flexion to the degree of V-V malalignment indicated that a V-V malalignment of 1.4° causes a change in contact force imbalance of 67 N. No clinically important changes in the laxities were found with the 2° or 4° malaligned femoral components. None of eight changes in laxities were strongly correlated (R2 0.5) with changes in medial contact force, lateral contact force, or contact force imbalance. Aim 3 KA TKA was performed on ten human cadaveric knee specimens. I-E malalignment was introduced using 3D printed femoral components which simulated errors in the joint line of 2° internal rotation, 4° internal rotation, 2° external rotation, and 4° external rotation. Contact forces were measured using a custom tibial force sensor. Laxities were measured using a six degree-of-freedom load application system. The correlation coefficient was computed for each combination of the eight changes in laxities and the changes in medial contact force, lateral contact force, and contact force imbalance. Statistically significant and clinically important changes in contact force imbalance occurred with the 4° internal component at 45° flexion (83 N), 60° flexion (110 N), 75° flexion (111 N), and 90° flexion (96 N) (p 0.0001). A statistically significant and clinically important change in the valgus laxity of 1.5° was found with 4° external component (p

By virtue of standardization of the TKA procedure, surgeons can nowadays solve the pain issue for the majority of the patients. Restoration of function is a goal of a different order and forms the scope of this book. The editors confronted today's leading knee surgeons with the limitations of current surgical techniques and technology. They challenged them to define new thresholds of functional capacity after Total Knee Arthroplasty. "A Guide to Get Better Performance in TKA" describes the cutting edge in surgical techniques, prosthetic design and achievement of excellent function for these patients.

Book excerpt: Worldwide experience with the Lcs• mobile bearing total knee prosthesis has been unpar alleled both in terms of enduring popularity and outstanding long-term clinical results. Buechel and Pappas's design was based on the principles of; restoring anatomical joint function to as near normal as possible, minimising contact stresses to avoid wear and darn age to the bearing surfaces. and finally the idea that constraint should refiect the need for mobility, to avoid shear stresses and loosening of the implant. In 1977, the LCS® knee was implanted by Dr. Frederick Buechel. This was the first mobile bearing, tri-compartmental knee implant. This was also the first to successfully address the key issues ofloosening, wear and patello-femoral problems associated with earlier designs. The unique design solution was the creation of a common articulating geometry for the tibia and patella on the distal femoral surface. This resulted in a tibial and patellar articulation that was mobile in nature, but with an identical radius of curvature and conformity. The mobile bearing concept was considered sufficiently novel and unproven that the US FDA (Food & Drug Administration) required that it be validated in an Investigational Device Evaluation (IDE). An FDA IDE study involving 25 US surgeons was initiated in 1981. Validation of the clinical success of the device in this study resulted in FDA approval of the LCS, Knee (for cemented, tri-compartmental use) in 1985.

Book excerpt: In this booklet, experts from across the world, including members of the ISAKOS Knee Arthroplasty Committee, offer clear, up-to-date guidance on all aspects of soft tissue or ligament balancing in primary total knee arthroplasty with the aim of enabling the reader to achieve optimal patient outcomes. After an introduction explaining the normal soft tissue condition in the native knee, surgical procedures are described, including techniques for the management of severe deformity. The most striking feature of the booklet, however, is the many pages devoted to the accurate evaluation and clinical relevance of ligament balancing. Different techniques and devices for intraoperative soft tissue assessment are discussed, highlighting, for example, the use of gap-measuring devices or trial liners with load-bearing sensors to achieve more objective evaluation. Above all, special attention is devoted to the crucial issue of the impact of intraoperative soft tissue balance on postoperative results. In the closing chapter, very experienced surgeons introduce intraoperative troubleshooting in order to assist successful completion of arthroplasty.

Book excerpt: Total knee arthroplasty (TKA) is a frequently performed operation - in the U.S. alone, 5.2 million TKAs were performed from 2000-2010 - and partial (unicompartmental) knee arthroplasty (UKA) is another common operation that is done in younger, active individuals. Many patients require knee arthroplasty from osteoarthritis that develops after sports injuries or decades of participation in athletics. While much has been written regarding technical surgical details of arthroplasty, there is comparably little available on critical rehabilitation principles and guidelines that allow return to normal physical function, as well as recreational and sports activities. Filling this gap in the literature, this group of internationally recognized surgeons and therapists discusses all aspects of critical rehabilitation following both partial and total knee replacement, including: Advances in surgical techniques for robotic computer-navigated knee arthroplasty Effects of preoperative rehabilitation and nutrition on postoperative function Specific rehabilitation principles to avoid complications and return to daily activities Advanced physical therapy concepts to return to recreational and sports activities Objective testing to determine strength and physical function in the arthroplasty athlete Recommended guidelines for recreational and sports activities Key factors for achieving high patient satisfaction and quality of life after surgery Presenting the most up-to-date evidence and guidelines, Critical Rehabilitation for Partial and Total Knee Arthroplasty will be an invaluable resource for orthopedic surgeons, physical therapists, athletic trainers, personal trainers and all professionals caring for patients seeking to return to full activity after knee replacement.

Available in PDF, EPUB and Kindle. Book excerpt: The approach to total hip and total knee arthroplasty is changing around the world. There is now a strong emphasis on a more rapid recovery and on more outpatient surgery. Each step of the process is now being modified with more thorough pre-operative evaluations, streamlined surgical approaches, rapid mobilization and faster return to normal activities. These changes place new pressures on all of the health care providers in the system. This unique text - the first of its kind - is a practical guide for each member of the clinical team with updates by the leading authorities from around the country. Each chapter addresses a specific issue and will outline the important new items that need to be addressed, very similar to a handbook. Topics covered include the implementation of new payment models and outcome measurements, recommendations to streamline the pre-, peri- and post-operative protocols, the utility and application of outpatient joint replacement programs, multimodal pain management and post-acute rehabilitation strategies. There is no publication at present that addresses all of these items together in one convenient place. Rapid Recovery in Total Joint Arthroplasty is written and edited by experienced clinicians and surgeons, sharing their years of experience to create a practical, up-to-date text useful for everyday work.

Available in PDF, EPUB and Kindle. Book excerpt: Covering both primary and revision total knee arthroplasty (TKA), each technique-oriented chapter in this book opens with a clinical case and an overview of the challenges and multiple options for management, and each section within the chapter will describe the physical exam, surgical approach, clinical outcome and recent supporting literature. Chapters will utilize bullet points for quick reference and plentiful intra-operative photos to illustrate the various techniques described. Part one covers primary TKA, with cases demonstrating management strategies for the varus and valgus knee, flexion contracture, patellofemoral arthritis, and extra-articular deformity, among others, while part two covers revision TKA, with cases demonstrating acute infection, flexion and global instability, severe tibial and femoral bone loss, and periprosthetic fracture, among others. Written and edited by experts in the field, Complex Cases In Total Knee Arthroplasty: A Collection of Current Techniques will be a useful reference for orthopedic surgeons, residents and fellows as well as sports medicine specialists and anyone involved in surgical care of the knee.

This book was released on 2009 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knee replacement surgery is often performed in cases where the pain due to knee osteoarthritis can no longer be effectively controlled by conservative measures. The surgery-which replaces the articular surfaces of the tibia, femur and sometimes the patella with a mix of metal and polyethylene-is one of the most commonly performed lower limb surgeries. Despite patient reports of reduced pain and increased participation in activities of daily living, knee function following total knee arthroplasty (TKA) does not return to normal. Reductions in both passive and active knee range of motion, alterations in magnitude and timing of muscle activity, and changes in knee joint kinetics have all been reported. Comparatively little is known about why knee function is altered following TKA. In an attempt to address this gap in the literature, this thesis was designed to examine the biomechanical factors thought to contribute to reduced knee extensor moments following TKA. In particular, the contribution of alterations in passive knee moments, muscle moment arm lengths, and muscle activation magnitude and timing were examined in detail to determine which factors contributed to reduced knee extensor moment following TKA.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the current clinical practice, outcome and the future development of Total Knee Arthroplasty (TKA) in surgical settings. A major objective of this work is to address “What is the optimal design and fixation of the implants we use for knee arthroplasty reconstruction? What are the gold standards? and, Can we do better?”. In an attempt to throw light on these questions, the authors evaluate data from clinical studies and assess various factors which may influence the long term outcome of TKA. Many variables such as age, severity, implant design and surgical techniques for appropriate component placement and soft tissue balancing are explored in great detail by expert surgeons in the field. Total Knee Arthroplasty: Long Term Outcomes will be a useful resource for recently qualified surgeons in search of an introduction to this topic and for more experienced surgeons seeking an in-depth critical review of current practices in TKA.
